Abstract
The utility model provides a rotary quantitative liquid supply valve. The valve body is provided with balance air holes, an air exhaust pipe, an air entering pipe and a liquid discharge pipe; a valve rod is provided with a quantitative liquid chamber, air exhaust holes, liquid entering holes, balance communication air holes. The utility model can be used for converting quantitative pressure liquid fuel in a fuel tank to atmospheric environment, and the liquid fuel smoothly flows into the preheater of the appliance and equipment of the liquid fuel; the utility model can be also used for converting the quantitative pressure fluid in a sealed container in the chemistry and physical processes to some procedure, which provides quantitative data to physical and chemical research. The utility model has the advantages of simple structure, high safety, convenient operation and maintenance, light weight and low cost.
Description
The utility model relates to a kind of rotary quantitative liquid supply valve, particularly a kind of quantitative liquid feeding valve that is used for liquid fuel apparatus and the preheating of liquid fuel engineering equipment facility.
The preheating of existing liquid fuel apparatus and liquid fuel engineering equipment facility, mainly be to adopt manual vessel in preheater, to attach liquid fuel, be difficult to what of control pre-heating fuel, having lacked needs adds once more, many and cause waste, also can make the liquid fuel outflow sometimes, flare is guided to outside the stove, cause many inconvenience and trouble, even unsafe.Recently, though there is the quantitative liquid feeding fuel-device to occur, but because of the pressure that can not bear in the fuel tank is joined secondary fuel tank in addition, but, secondary fuel tank has certain volume, thereby it requires main fuel tank to abdicate the volume that certain space has dwindled main fuel tank, has increased the number of times of manual vessel annex solution fluid fuel, and brings many inconvenience and trouble for the manufacturing and the installation of fuel tank.Therefore, vessel attach liquid fuel by hand, have influenced the promotion and application of liquid fuel apparatus and liquid fuel engineering equipment facility to a certain extent.
The purpose of this utility model is: for liquid fuel apparatus and liquid fuel engineering equipment facility provide a kind of simple in structure, safe and reliable, use is easy to maintenance, volume is little, in light weight.Quantitative liquid feeding heat-riser valve with low cost.
Another purpose of the present utility model is: for the seal fluid pressurized container in chemical engineering and the physical engineering process provides a kind of quantitative pressure fluid transfer valve, quantitative pressure fluid is transferred to from above-mentioned seal fluid pressurized container in the vessel in the atmosphere environment reposefully, for the research and the adjustment of chemical engineering and physical process provides quantitative data.
The technological scheme of a kind of rotary quantitative liquid supply valve that achieves the above object is to comprise valve body (1), valve rod (2), it is characterized in that valve body (1) for the hollow cone stage body of balance pore (11), outlet pipe (7), liquid inlet pipe (8), liquid discharging tube (12) is arranged, valve rod (2) is communicated with the circular cone stage body of pore (13) for quantitative liquid chamber (6), exhaust port (10), inlet opening (9), taphole (14) balance are arranged.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1: tapered quantitative liquid feeding valve sectional view.
Fig. 2: awl column type quantitative liquid feeding valve sectional view.
In Fig. 1 and Fig. 2, the name of each parts is called:
(1) valve body (2) valve rod (3) packing ring
(4) the quantitative liquid chamber of end cap (5) knob (6)
(7) outlet pipe (8) liquid inlet pipe (9) inlet opening
(10) exhaust port (11) balance pore (12) liquid discharging tube
(13) balance is communicated with pore (14) taphole
Overall structure of the present utility model is described as follows: have valve body (1), and valve rod (2), packing ring (3), the inside of valve body (1) is that the circular cone stage body of hollow cone stage body and valve rod (2) outer surface mates mutually.Also can extend and be the cylinder assemblying body at the small end of the circular cone stage body of valve body (1) and valve rod (2).Valve rod (2) is installed in the valve body (1), with screw valve body (1) valve rod (2), packing ring (3), end cap (4) are tightened to one, valve body (1) and valve rod (2) are closely cooperated do not leak, wherein valve body (1), valve rod (2), end cap (4) are all made with metal.Present embodiment is made with copper, aluminium or alloy.Upward have balance pore (11) at valve body (1), and liquid discharging tube (12) is set, outlet pipe (7), liquid inlet pipe (8) are set at its other end at hollow cone stage body small end.On valve rod (2), have quantitative liquid chamber (6) and have the balance that is complementary with valve body (1) and be communicated with pore (13), taphole (14), exhaust port (10), inlet opening (9), exhaust port (7), suction tude (8) are inserted the upper and lower part of seal fluid pressurized container respectively, wherein liquid inlet pipe (8) must insert in the liquid phase of seal fluid pressurized container bottom, outlet pipe (7) must be installed in liquid inlet pipe above, the distance up and down of two pipes is greater than the outer diameter of valve body (1).
When needs take out quantitative pressure fluid fuel from the seal fluid pressurized container, at first with the exhaust port (10) of valve rod (2), inlet hole (9), with outlet pipe (7), liquid inlet pipe (8) is aligned with each other, quantitatively pressure fluid will enter quantitative liquid chamber (6) automatically, rotation valve rod (2) then, make balance be communicated with pore (13), liquid-entering hole (14) respectively and the balance pore (11) of valve body (1), liquid discharging tube (12) is aligned with each other, quantitatively pressure fluid will be transferred in the atmosphere environment from quantitative liquid chamber (6), and flow in the preheater reposefully, thereby guaranteed the safe and reliable of warm.If the quantitative pressure fluid in chemical engineering and the physical process is transferred to from sealed pressure vessel in the atmosphere environment, just can provide quantitative data for the research of chemical engineering and physical process, generation and research are in time adjusted.
According to different purposes and various needs, different volumes and shape can be made in the quantitative liquid feeding chamber of quantitative liquid feeding valve.Therefore, the utility model has wide practical use.
